Abstract

Analyses of the lipid constituents of three temperate lacustrine sediments (Rostherne Mere, Esthwaite Water and Grasmere, Great Britain) and three sub-tropical lagoonal/tidal flat sediments (U.S. Virgin Islands, Rockhampton, Qld., Australia and Port Moresby, Papua, New Guinea) indicate the presence of straight-chain components attributable to autochthonous and allochthonous sources. Despite broad similarities in carbon-number distributions, minor differences observed in the respective hydrocarbon and in the respective fatty-acid compositions of the various sediments reflect differences in the sedimentary environments. Lipid constituents obtained by organic solvent extraction following acid hydrolysis appear to include a larger bacterial contribution than that observed in the lipids extracted by solvent alone.
